rlwrap: warning: k crashed, killed by SIGSEGV (core dumped).
rlwrap itself has not crashed, but for transparency,
it will now kill itself with the same signal

warnings can be silenced by the --no-warnings (-n) option
Segmentation fault (core dumped)

Seems like the crash doesn't always happen right away, and the "garbage text" is different each time I restart Kona.
